How to activate drag n drop in 21.04 [duplicate]

So below is my OS version and I've read that in this version of ubuntu there's a drag n drop function implemented. Somehow it doesn't work: I can't neither drag n drop files to browser upload window nor drag n drop them from folder to for an example desktop. I know that there's gnome extension called Desktop Icons, but I can't install it because of en error that says:

"Can't install "Desktop Icons" because this is an extension enabled by my current mode, I can't install manually any update in this session. "

thank you beforehand!

Solution 1:

Drag and Drop has been a problem since Nautilus stopped handling the Desktop in Ubuntu 20.xx. Gnome-shell extensions have tried to take on that job, with limited success. Here's a newer version that might work for you.

Use the Extensions app to disable the original "Desktop Icons" gnome-shell extension.

Install "Desktop Icons NG" (DING for short) gnome-shell extension, which can be found at https://extensions.gnome.org/extension/2087/desktop-icons-ng-ding/.

Right-click on the Desktop and choose "Settings" to set prefs for DING.
